testShout
� self. Nothing more expected ->assert: ( 'Do not panic' shout = "DO NO PANIC")

There are some things wrong with the second line:

there�s a period after self, you must remove it
you wrote NO instead of NOT, so the the assert will fail
the sentence in capitals is surrounded by double quotes $" which are for comments; strings are surrounded by single quotes $' , this makes your code actually be:

( 'Do not panic' shout = )

To write the return operator, ^, I can use one of these two combinations in my linux box (which has a slightly weird US international keyboard layout):

press shift+6 twice
press shift+6, then press space

As an additional note, you don�t actually need the parentheses there, because the order of evaluation is:

unary messages (#shout)
binary messages (#=)
keyword messages (#assert:)

So you can write:

testShout

^ self assert: 'do not panic' shout = 'DO NOT PANIC'

Hope this helps in getting a better grasp of Smalltalk syntax. I found it really easy and fun to learn :)

Cheers,
